67; BN 213-9. Superb EF, underlying luster, small mark on cheek. Fine
style, and extremely well struck from fresh dies. Ex John Whitney
Walter Collection (Stack’s, 29 November 1990), lot 26 (enlarged on pp.
15 and 66); Leu 38 (13 May 1986), lot 239. This reverse type
commemorates the protection of Nero from the Pisonian Conspiracy.
Events of the years 64-65 AD defined the subsequent reputation of Nero
as a cruel and self-indulgent ruler. His "excesses" resulted in a
conspiracy to overthrow and replace him with Gaius Calpurnius Piso.
Among the conspirators were many high-ranking members of Nero's court
including Seneca the Younger, the poet Lucan, and Petronius, who called
himself Nero's "arbiter of elegance." To Nero, the failure of a
conspiracy made up of those so close to him could have been achieved
only through divine intervention. As the king of the Gods oversaw the
security of the Roman state, Nero believed it was Jupiter the Guardian
(Custos) who had saved him from harm. Estimate: 10000 USD.

Augustus, 54 - 68 No.: 37 Schätzpreis - Estimate CHF 9000.- Aureus
circa 66-67, 7.32 g. IMP NERO CAESAR - AVGVSTVS Laureate head r. Rev.
IVPPITER - CVSTOS Jupiter, bare to waist, seated l. on throne, holding
a thunderbolt in l. hand and long sceptre in l. RIC 63. BMC 77. C 120.
CBN 231. Vagi 683. Calicó 413. Boscoreale tone and extremely
fine. Ex Ponterio sale 74, 1995, 261. On this issue there is a
significant shift in Nero's inscription, with the IMP moving from the
end (where it had been prior to the change in 66), to the beginning of
his inscription - thus changing from acognomen to a praenomen. Not only
is this important to establishing an internal chronology for Nero's
coinage, it is an indicator of the declining character of what remained
of his reign. Suetonius recognized its importance, for it is the only
salutation of Nero he mentions other than those he accepted upon his
accession. Suetonius is careful to contrast Nero with Claudius in this
regard, for Claudius did not add to his own dignity in this manner.

Price 4750 USD Description NERO. 54-68 AD. AV Aureus (7.39 g,

BMCRE 67; Cohen 118. Good VF, a few minor marks. ($3000) This reverse
type commemorates the protection of Nero from the Pisonian Conspiracy.
Events of the years 64-65 AD defined the subsequent reputation of Nero
as a cruel and self-indulgent ruler. In 64 AD, a large section of
central Rome burned; Nero's reputed singing of the destruction of Troy
during the fire led to the later association of him "fiddling" as the
city burned. Within the charred remains of the city's center, Nero
constructed the Domus Aurea, or Golden House, so named because of the
gilded tiles on its exterior. Nero's "excesses" resulted in a
conspiracy to overthrow and replace him with Gaius Calpurnius Piso.
Among the conspirators were many high-ranking members of Nero's court
including Seneca the Younger, the poet Lucan, and Petronius, who called
himself Nero's "arbiter of elegance." To Nero, the failure of a
conspiracy made up of those so close to him could have been achieved
only through divine intervention. As the king of the Gods oversaw the
sÉcurity of the Roman state, Nero believed it was Jupiter the
Guardian (Custos) who had saved him from harm. Estimate: $3000.
